Sagot :
Answer:
-47
Step-by-step explanation:
First you use PEMDAS, so you start with the exponent.
-5^2 = 25
Then you multiply the -2!!! Not the 2 with the 25, multiplying the 2 is a common mistake.
When you multiply the -2, it results in:
3 - 50
= -47
Answer:
-47
Step-by-step explanation:
Original Equation:
[tex]f(-5)=3-2(-5)^2[/tex]
Square the -5 (this cancels out the negative sign
[tex]f(-5)=3-2(25)[/tex]
Multiply 2 and 25
[tex]f(-5) = 3-50[/tex]
Subtract 50 from 3
[tex]f(-3) = -47[/tex]
I'm a bit confused by what you mean factor the equation? Given the context. But I'm going to assume the equation is: [tex]f(x)=3-2x^2[/tex]. Which isn't exactly factorable.
